This shot is actually a composite of three different RAW conversions
of the same file. To get the saturation in the sky the exposure of the
trees and walkway would have been pure black. So I processed one layer
to highlight the warm sunlight as it was coming down in the middle, one
layer to catch the rich blue above it and on the water and then one
conversion to extract the details on the trees and the shoreline.
The final was blended in CS3 by hand. Hope you like it.
